Question

Find the domain and range of this function

Answer 1

\(\large \color{black}{\begin{align} f(x)=|x|\hspace{.33em}\\~\\
\end{align}}\)

Answer 2

for the domain, you have to look where the x exists, which is in the whole section of R, you understand?

Answer 3

For the range you have to look to the graph, and where it all exists on the Y-scale (the vertical one)

Answer 4

x is all negative and positive values

Answer 5

That's right, and Y?

Answer 6

y is positive values

Answer 7

Indeed, so the x values are the domain and the y-values are the range.

Answer 8

how to write this in standard form

Answer 9

Domain: ] -infinity, infinity[
Range : [0, infinity[
(that's how they write it in our region)

Answer 10

i have to write like this
f(x)=x^2

domain of f ={x:x\(\in\) R}
